Attention deficit hyperactivity disorder (ADHD)1 - is a group of behavioural symptoms that include inattentiveness, hyperactivity and impulsiveness.

Common symptoms of ADHD include:

a short attention span or being easily distracted

restlessness, constant fidgeting or overactivity

being impulsive

Symptoms of ADHD tend to be first noticed at an early age, and may become more noticeable when a child's circumstances change, such as when they start school. Most cases are diagnosed in children between the ages of 6 and 12.

The symptoms of ADHD usually improve with age, but many adults who are diagnosed with the condition at a young age will continue to experience problems.
